<P>PROBLEM TO BE SOLVED: To obtain a high capacity electrode active material in the electrode active material as the main body having amorphous iron phosphoric acid complex expressed by A<SB>x</SB>MP<SB>y</SB>O<SB>z</SB>. <P>SOLUTION: This is the electrode active material as the main body having amorphous transitiion metal complex expressed by the A<SB>x</SB>MP<SB>y</SB>O<SB>z</SB>(in the formula, x and y independently satisfy 0≤x≤2 and 0≤y≤2, z is expressed by z=(x+5y+valence number of M)/2 to satisfy stoichiometry. Moreover, A is alkaline metal, and M is a metal element selected from transition metals), and which has a peak in the vicinity of 220 cm<SP>-1</SP>in Raman spectra. <P>COPYRIGHT: (C)2008,JPO&INPIT |
